| 英文摘要 | The binary of blend poly {4,8-bis [5-(2-ethylhexyl) thiophen-2-yl] benzo [1,2-b : 4,5-b'] dithiophe-ne-alt-3-flu-orothieno [3,4-b] thiophene-2-carboxy-late}(PTB7-Th) : poly{[N, N-bis(2-octyldode-cyl)-napthalene-1,4,5,8-bis(dicarboximide)-2,6-diyl]-alt-5,5'-(2,2'-bithiophene)}(N2200)(PTB7-Th : N2200) active layer films were annealed by methanol solvent-The difference of contact potential between active layer and gold-coated tip were increased from 37 mV to 160 mV, which means the surface work function decreased from 4.71 eV to 4.59 eV-XPS result showed that more N2200 diffused to surface of active layer during vapor annealing because there was a stronger interaction between poor polar solvent methanol and N2200-Such diffusion lead to the decrease of work function which was beneficial to promote energy match between electrode and active layer and the formation of better ohmic contact, which resulted in the over 10% enhance of power conversion efficiency of corresponding organic solar cells. |
